West Nile Virus Found in Benton County

The Benton County Mosquito Control District routinely collects and tests mosquitoes for the presence of West Nile virus (WNv).  On June 26th, we had our first positive mosquito sample of the 2018 season.  Please click here to be taken to a map on the approximate location of the mosquito sample.

Please note:  West Nile virus is carried by birds and transmitted by mosquitoes, so the virus can be moved throughout areas relatively quickly.  Also, the District is unable to trap and test mosquitoes from everywhere; our data serves as an early detection system but should not be assumed to show every location where WNv could be present.  A CDC (Centers for Disease Control) approved insect repellent is your best defense against mosquito bites when outdoors.  The District is and will continue to perform mosquito control activities and monitoring of mosquito populations.

The Benton County Mosquito Control District is dedicated to responsibly improving the quality of life and increasing public education in our area. The District accomplishes this by utilizing Integrated Pest Management (IPM) strategies. IPM is designed to utilize cost-effective control measures to reduce mosquito populations and the diseases they potentially carry, while being environmentally sensitive.

Communication and cooperation with property owners, residents and governmental agencies are critical components in the effort to reduce mosquito populations. Benton County MCD strives to be open and responsive to our community.
